Constructor Detail

### KeyTransRecipientInfo

    public KeyTransRecipientInfo(RecipientIdentifier rid,
                                 AlgorithmIdentifier keyEncryptionAlgorithm,
                                 ASN1OctetString encryptedKey)

Method Detail

### getInstance

    public static KeyTransRecipientInfo getInstance(java.lang.Object obj)

  Return a KeyTransRecipientInfo object from the given object.

  Accepted inputs: null → null `KeyTransRecipientInfo` object `ASN1Sequence` input formats with KeyTransRecipientInfo structure inside

  Parameters:
    `obj` - the object we want converted.
  Throws:
    `java.lang.IllegalArgumentException` - if the object cannot be converted.

### getVersion

    public ASN1Integer getVersion()

### getRecipientIdentifier

    public RecipientIdentifier getRecipientIdentifier()

### getKeyEncryptionAlgorithm

    public AlgorithmIdentifier getKeyEncryptionAlgorithm()

### getEncryptedKey

    public ASN1OctetString getEncryptedKey()

### toASN1Primitive

    public ASN1Primitive toASN1Primitive()

  Produce an object suitable for an ASN1OutputStream.

  Specified by:
    `toASN1Primitive` in interface `ASN1Encodable`
  Specified by:
    `toASN1Primitive` in class `ASN1Object`
  Returns:
    a primitive representation of this object.
